The reactions described hereinbefore and hereinafter are carried out in a manner known per se, for example in the absence or, as a rule, in the presence of a suitable solvent or diluent or a mixture of these, the process being carried out, as required, with cooling, at room temperature or with heating, for example in a temperature range from approx. -80° C. to the boiling point of the reaction medium, preferably from approx. -20° C. to approx. +150° C., for example at the reflux temperature of the reaction mixture and, if necessary, in a sealed vessel, under pressure, in an inert gas atmosphere and/or under anhydrous conditions. Particularly advantageous reaction conditions can be seen from the examples. The starting material described hereinbefore and hereinafter, which is used for the preparation of the compounds I, is known or can be prepared by methods known per se, for example following the information given hereinafter.

Variant a):

Suitable acidic catalysts are, for example, sulfonic acids such as methane- or p-toluenesulfonic acid, including the acidic ion-exchanger resins having sulfo groups, Lewis acids such as boron trifluoride/diethyl ether complexes or boron trifluoride/dimethyl ether complexes, as well as mineral acids such as sulfuric acid or phosphoric acid.

The reactants can be reacted with each other as such, i.e. without an addition of a solvent or diluent, for example in the melt. However, in most cases it is advantageous to add an inert solvent or diluent or a mixture of these. Examples of such solvents or diluents which may be mentioned are: aromatic, aliphatic and alicyclic hydrocarbons and halohydrocarbons such as benzene, toluene, xylene, chlorobenzene, bromobenzene, petroleum ether, hexane, cyclohexane, dichloromethane, trichloromethane, dichloroethane or trichloroethene; ethers such as diethyl ether, tert-butyl methyl ether, tetrahydrofuran or dioxane; ketones such as acetone or methyl ethyl ketone; amides such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone or hexamethylphosphoric triamide; nitriles such as acetonitrile; and sulfoxides such as dimethyl sulfoxide.

The reaction is carried out advantageously in a temperature range from approx. 0° C. to approx. +180° C., preferably from approx. +20° C. to approx. ⊕130° C., in many cases at the reflux temperature of the solvent used.

In a preferred embodiment of variant a), a compound II is reacted with a compound III at reflux temperature, in an aromatic hydrocarbon, preferably in toluene, and in the presence of a sulfonic acid as catalyst, preferably in the presence of p-toluenesulfonic acid.

The compounds II are known or can be prepared in analogy to known compounds, for example by reacting a compound of the formula IV with 2-R₅ -2,3-epoxypropan-1-ol, the process being carried out in a manner known per se, advantageously in an inert solvent or diluent, for example of the abovementioned type, for example in an aromatic hydrocarbon such as toluene or xylene, in the presence of a catalyst, for example a quaternary ammonium salt, such as in the presence of tetramethylammonium chloride, and at room temperature or increased temperature, for example in a temperature range from approx. 20° C. to approx. 200° C., preferably from approx. 50° C. to approx. 150° C.

The compounds of the formula III are known or can be prepared in analogy to known compounds.

The compounds IV are known or can be prepared in analogy to known compounds.

Variant b):

Bases which are suitable for facilitating the elimination of HZ are, for example, hydroxides, hydrides, amides, alkanolates, carbonates, dialkylamides or alkylsilylamides of alkali metals or alkaline earth metals, or alkylamines, alkylenediamines, free or N-alkylated saturated or unsaturated cycloalkylamines, basic heterocycles, ammonium hydroxides and carbocyclic amines. Examples which may be mentioned are sodium hydroxide, sodium hydride, sodium amide, sodium methanolate, sodium carbonate, potassium tert-butanolate, potassium carbonate, lithium diisopropylamide, potassium bis(trimethylsilyl)amide, calcium hydride, triethylamine, triethylenediamine, cyclohexylamine, N-cyclohexyl-N,N-dimethylamine, N,N-diethylaniline, pyridine; 4-(N,N-dimethylamino)pyridine, N-methylmorpholine, benzyltrimethylammonium hydroxide as well as 1,5-diazabicyclo[5.4.0]undec-5-ene(DBU).

The reaction is carried out advantageously in an inert solvent or diluent, for example of the type mentioned under variant a), and in a temperature range from approx. -80° C. to approx. +200° C., for example from approx. -20° C. to approx. +100° C.

The compounds of the formula V are known or can be prepared in analogy to known compounds.

Variant c):

Suitable acidic catalysts are, for example, of the type mentioned under variant a) for the reaction of compounds II and III.

The reaction is carried out advantageously in an inert solvent or diluent, for example of the type mentioned under variant a), and in a temperature range from approx. 0° C. to approx. +180° C., preferably from approx. +20° C. to approx. +130° C., frequently at the reflux temperature of the solvent used.

The compounds of the formula VI are known or can be prepared in analogy to known compounds.

The compounds I can exist in the form of one of the possible isomers or as a mixture of these, for example as pure isomers, such as antipodes and/or diastereomers, or as isomer mixtures, such as enantiomer mixtures, for example racemates, diastereomer mixtures or racemate mixtures, depending on the number and the absolute and relative configuration of the asymmetric carbon atoms; the invention relates to the pure isomers and to all possible isomer mixtures and is to be understood correspondingly in each case hereinbefore and hereinafter even when stereochemical details are not mentioned specifically in each case.

Diastereomer mixtures and racemate mixtures of compounds I which can be obtained according to the process--depending on the choice of starting materials and the procedures--or by other routes can be resolved in a known manner on the basis of the physicochemical differences of the components to give the pure diastereomers or racemates, for example by fractional crystallisation, distillation and/or chromatography.

Enantiomer mixtures which can be obtained accordingly, such as racemates, can be resolved by known methods to give the optical antipodes, for example by recrystallisation from an optically active solvent, by chromatography on chiral adsorbents, for example high-pressure liquid chromatography (HPLC) on acetylcellulose, with the aid of suitable microorganisms, by cleavage with specific, immobilised enzymes, via the formation of inclusion compounds, for example using chiral crown ethers, where only one enantiomer is complexed.

Pure diastereomers or enantiomers can be obtained according to the invention not only by separating corresponding isomer mixtures but also by generally known methods of diastereoselective or enantioselective synthesis, for example by carrying out the process according to the invention with educts whose stereochemistry is suitable.

It is advantageous to isolate or synthesise in each case the biologically more active isomer, for example enantiomer, or isomer mixture, for example enantiomer mixture, if the individual components differ in their biological activity.

The compounds I can also be obtained in the form of their hydrates and/or include other solvents, for example those which may have been used for the crystallisation of compounds in solid form.

The invention relates to all those embodiments of the process which start from a compound which can be obtained in any desired step of the process as starting material or intermediate and in which all or some of the missing steps are carried out, or in which a starting material in the form of a derivative or salt and/or racemates or antipodes thereof are used or, in particular, formed under the reaction conditions.

The process of the present invention preferably uses those starting materials and intermediates which lead to the compounds I which have been described at the outset as being particularly valuable.

In particular, the invention relates to the preparation processes described in Examples H1 to H5.

The invention also relates to starting materials and intermediates which are used according to the invention for the preparation of the compounds I and which are novel, and to their use and to processes for their preparation.

In this context, the compounds II, which are also part of the present invention, and their preparation and their use as intermediates are of particular importance.

Dioxolanes which are substituted in the 4-position and which have a similar structure have already been disclosed, for example in the European patent application with the Publication Number 0 411 676. The compounds I of the present invention differ from these known compounds in structural terms in a characteristic manner in that they are substituted in the 2-position of the phenyl ring of the phenoxymethyl group shown in formula I by C₁ -C₃ alkyl, halo-C₁ -C₃ alkyl, C₁ -C₃ alkoxy, halo-C₁ -C₃ alkoxy, fluorine, chlorine or bromine (R₂); moreover, the compounds I of the present invention have an activity in the field of pest control which is increased to a surprising extent.

The compounds I of the present invention are oils, resins or solids which are stable at room temperature. While having a favourable tolerability for warm-blooded species, fish and plants, they are valuable active ingredients in the field of pest control. The active ingredients according to the invention are particularly active against insects and arachnids, as they can be found on useful plants and ornamentals in agriculture and horticulture, in particular in rice, cotton, vegetable and fruit crops, and in forests. The compounds I are particularly suitable for controlling insects in crops of rice, fruit and vegetables, in particular for controlling plant-injurious insects such as Nilaparvata lugens and Heliothis virescens. Other fields in which the active ingredients according to the invention can be applied are the protection of stored goods and of materials, and in the hygiene sector, in particular the protection of domestic animals and productive livestock. The compounds I are active against all or individual development stages of normally-sensitive, but also resistant pests species.

The good pesticidal activity of the compounds I according to the invention is reflected in a destruction rate (mortality) of at least 50-60% of the abovementioned pests.

The activity of the compounds I according to the invention and the compositions comprising them can be broadened substantially and adapted to prevailing circumstances by adding other insecticides and/or acaricides. Suitable additions are, for example, representatives of the following classes of active ingredients: organophosphorus compounds, nitrophenols and derivatives, formamidines, ureas, carbamates, pyrethroids, chlorinated hydrocarbons and Bacillus thuringiensis preparations.

The compounds I are employed as pure active ingredients or, preferably, together with the auxiliaries conventionally used in the art of formulation, and they can therefore be processed in a known manner to give, for example, emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts and granules, and also encapsulations in polymeric substances. The application methods such as spraying, atomising, dusting, scattering or pouring, as well as the compositions are selected to suit the intended aims and the prevailing circumstances. The compounds I are furthermore suitable for use in the treatment of seed. The seed can be treated or dressed with the active ingredient, or a formulation comprising the active ingredient, before sowing, or the active ingredient can be applied to the seed furrow during sowing:

The formulations, i.e. the compositions, preparations or combinations comprising the active ingredient of the formula I, or a combination of this active ingredient with other insecticides and/or acaricides, and, if desired, solid or liquid adjuvants, are prepared in a known manner, for example by intimately mixing and/or grinding the active ingredient with the adjuvants such as extenders, for example solvents or solid carriers, or such as surface-active compounds (surfactants).

The following are suitable as solvents: aromatic hydrocarbons, preferably the fractions C₈ to C₁₂ of alkylbenzenes such as xylene mixtures or alkylated naphthalenes, aliphatic or cycloaliphatic hydrocarbons such as cyclohexane, paraffins or tetrahydronaphthalene, alcohols such as ethanol, propanol or butanol, glycols as well as their ethers and esters such as propylene glycol, dipropylene glycol ether, ethylene glycol, ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or N,N-dimethylformamide, water and epoxidised or unepoxidised vegetable oils such as epoxidised or unepoxidised rapeseed oil, castor oil, coconut oil or soya oil; silicone oils may also be used.

Solid carriers which are suitable, for example for dusts and dispersible powders, are, as a rule, ground natural minerals, such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly-disperse silicas or highly-disperse absorptive polymers. Possible particulate, adsorptive carriers for granules are either porous types such as pumice, crushed brick, sepiolite or bentonite, or non-sorptive carrier materials, such as calcite or sand. Moreover, a large number of granulated materials of inorganic or organic nature can be used, in particular dolomite or comminuted plant residues.

Suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants which have good emulsifying, dispersing and wetting properties, depending on the nature of the active ingredient I to be formulated or of the combination of this active ingredient with other insecticides and/or acaricides. Surfactants are also to be understood as meaning mixtures of surfactants.

Suitable non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols which can contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenols. Also suitable are the water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopolypropylene glycol and alkyl polypropylene glycol which have 1 to 10 carbon atoms in the alkyl chain and contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. As a rule, the compounds mentioned contain 1 to 5 ethylene glycol units per propylene glycol unit. Examples of non-ionic surfactants which may be mentioned are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Other suitable substances are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.

The cationic surfactants are mainly quaternary ammonium salts which contain at least one alkyl radical having 8 to 22 C atoms as N substituents and which have lower halogenated or free alkyl, benzyl or lower hydroxyalkyl radicals as further substituents. The salts are preferably in the form of halides, methyl sulfates or ethyl sulfates, for example stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.

Suitable anionic surfactants can be either so-called water-soluble soaps or water-soluble synthetic surface-active compounds. Soaps which are suitable are the alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts of higher fatty acids (C₁₀ -C₂₂) such as the sodium salts or potassium salts of oleic or stearic acid, or of natural mixtures of fatty acids which can be obtained, for example, from coconut oil or tall oil; mention must also be made of the fatty acid methyltaurinates. However, so-called synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or fatty sulfates are, as a rule, in the form of alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts and have, as a rule, an alkyl radical having 8 to 22 C atoms, alkyl also including the alkyl moiety of acyl radicals; examples which may be mentioned are the sodium salt or calcium salt of ligninsulfonic acid, of dodecylsulfuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulfuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfo groups and a fatty acid radical having approx. 8-22 C atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolammonium salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensation product. Other suitable compounds are the corresponding phosphates, such as salts of the phosphoric ester of a p-nonylphenol/(4-14)-ethylene oxide adduct, or phospholipids.

The abovementioned surfactants are only to be understood as being examples; a large number of further surfactants which are conventionally used in the art of formulation and which are suitable according to the invention are described in the specialist literature.

As a rule, the pesticidal compositions comprise 0.1 to 99%, in particular 0.1 to 95%, of active ingredient I or of the combination of this active ingredient with other insecticides and/or acaricides and 1 to 99.9%, in particular 5 to 99.9%, of a solid or liquid adjuvant, and, as a rule, 0 to 25%, in particular 0.1 to 20% of the preparations can be composed of surfactants (% is in each case to be understood as meaning percent by weight). While concentrated compositions are more preferred as commercial goods, the end user usually uses dilute compositions with much lower concentrations of active ingredient. Typical use concentrations are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm. As a rule, the application rates per hectare are 1 to 1000 g of active ingredient per hectare, preferably 25 to 500 g/ha.

Preferred formulations have, in particular, the following composition (%=percent by weight):

Emulsifiable concentrates:

Active ingredient: 1 to 90%, preferably 5 to 20%

Surfactant: 1 to 30%, preferably 10 to 20%

Liquid carrier: 5 to 94%, preferably 70 to 85%

Dusts:

Active ingredient: 0.1 to 10%, preferably 0.1 to 1%

Solid carrier: 99.9 to 90%, preferably 99.9 to 99%

Suspension concentrates:

Active ingredient: 5 to 75%, preferably 10 to 50%

Water: 94 to 24%, preferably 88 to 30%

Surfactant: 1 to 40%, preferably 2 to 30%

Wettable powders:

Active ingredient: 0.5 to 90%, preferably 1 to 80%

Surfactant: 0.5 to 20%, preferably 1 to 15%

Solid carrier: 5 to 95%, preferably 15 to 90%

Granules:

Active ingredient: 0.5 to 30%, preferably 3 to 15%

Solid carrier: 99.5 to 70%, preferably 97 to 85%

The preparations can also comprise further adjuvants such as stabilisers, for example epoxidised or unepoxidised vegetable oils (for example epoxidised coconut oil, rapeseed oil or soya oil), defoamers, for example silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, as well as fertilisers or other active ingredients for achieving specific effects.

The invention also embraces a method of controlling the abovementioned pests, which is distinguished by applying an active ingredient of the formula I, or a composition according to the invention which comprises an active ingredient of the formula I, to the pests or the various development stages of the pests, or to their locus.

The examples which follow illustrate the above-described invention without imposing any limitation to its scope."n_(D) ^(T) " is the refractive index at a temperature of T° C. Temperatures are given in degrees Celsius. "m.p." is the melting point; "%" is percent by weight, unless otherwise indicated. Compounds I in which R₁ and R₄ are different can form diastereomers; "A" and "B" are in each case the two separated diastereomer components of such mixtures; if, however, no symbols "A" and "B" are given, the product is a diastereomer mixture.

PREPARATION EXAMPLES EXAMPLE H1

3-(2-Chloro-4-phenoxyphenoxy)-1,2-dihydroxypropane ##STR9##

0.2 g of tetramethylammonium chloride is added to a solution of 22.1 g (0.1 mol) of 2-chloro-4-phenoxyphenol in 20 ml of xylene, the mixture is heated at 60° C., and 8.1 g of 2,3-epoxypropan-1-ol are added dropwise with stirring in the course of 20 minutes. Stirring of the reaction mixture is then continued for 8 hours at 90° C., 60 ml of hexane are added with stirring at 60° C. in the course of 5 minutes, the mixture is cooled to 0° C., and the solid which has precipitated is filtered off. The crude product obtained is recrystallised in isopropanol/hexane. Colourless crystals of the title compound with a melting point of 87°-88° C. (Compound No. 1.13) are obtained.
